Merge tag 'net-next-6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Paolo Abeni: "Core:
- Implement the Device Memory TCP transmit path, allowing zero-copy data transmission on top of TCP from e.g. GPU memory to the wire.
- Move all the IPv6 routing tables management outside the RTNL scope, under its own lock and RCU. The route control path is now 3x times faster.
- Convert queue related netlink ops to instance lock, reducing again the scope of the RTNL lock. This improves the control plane scalability.
- Refactor the software crc32c implementation, removing unneeded abstraction layers and improving significantly the related micro-benchmarks.
- Optimize the GRO engine for UDP-tunneled traffic, for a 10% performance improvement in related stream tests.
- Cover more per-CPU storage with local nested BH locking; this is a prep work to remove the current per-CPU lock in local_bh_disable() on PREMPT_RT.
- Introduce and use nlmsg_payload helper, combining buffer bounds verification with accessing payload carried by netlink messages.
Netfilter:
- Rewrite the procfs conntrack table implementation, improving considerably the dump performance. A lot of user-space tools still use this interface.
- Implement support for wildcard netdevice in netdev basechain and flowtables.
- Integrate conntrack information into nft trace infrastructure.
- Export set count and backend name to userspace, for better introspection.
BPF:
- BPF qdisc support: BPF-qdisc can be implemented with BPF struct_ops programs and can be controlled in similar way to traditional qdiscs using the "tc qdisc" command.
- Refactor the UDP socket iterator, addressing long standing issues WRT duplicate hits or missed sockets.
Protocols:
- Improve TCP receive buffer auto-tuning and increase the default upper bound for the receive buffer; overall this improves the single flow maximum thoughput on 200Gbs link by over 60%.
- Add AFS GSSAPI security class to AF_RXRPC; it provides transport security for connections to the AFS fileserver and VL server.
- Improve TCP multipath routing, so that the sources address always matches the nexthop device.
- Introduce SO_PASSRIGHTS for AF_UNIX, to allow disabling SCM_RIGHTS, and thus preventing DoS caused by passing around problematic FDs.
- Retire DCCP socket. DCCP only receives updates for bugs, and major distros disable it by default. Its removal allows for better organisation of TCP fields to reduce the number of cache lines hit in the fast path.
- Extend TCP drop-reason support to cover PAWS checks.
Driver API:
- Reorganize PTP ioctl flag support to require an explicit opt-in for the drivers, avoiding the problem of drivers not rejecting new unsupported flags.
- Converted several device drivers to timestamping APIs.
- Introduce per-PHY ethtool dump helpers, improving the support for dump operations targeting PHYs.
Tests and tooling:
- Add support for classic netlink in user space C codegen, so that ynl-c can now read, create and modify links, routes addresses and qdisc layer configuration.
- Add ynl sub-types for binary attributes, allowing ynl-c to output known struct instead of raw binary data, clarifying the classic netlink output.
- Extend MPTCP selftests to improve the code-coverage.
- Add tests for XDP tail adjustment in AF_XDP.
New hardware / drivers:
- OpenVPN virtual driver: offload OpenVPN data channels processing to the kernel-space, increasing the data transfer throughput WRT the user-space implementation.
- Renesas glue driver for the gigabit ethernet RZ/V2H(P) SoC.
- Broadcom asp-v3.0 ethernet driver.
- AMD Renoir ethernet device.

- Aeonsemi 10G C45 PHYs driver.

Tony Nguyen says:
==================== idpf: add initial PTP support
Milena Olech says:
This patch series introduces support for Precision Time Protocol (PTP) to Intel(R) Infrastructure Data Path Function (IDPF) driver. PTP feature is supported when the PTP capability is negotiated with the Control Plane (CP). IDPF creates a PTP clock and sets a set of supported functions.
During the PTP initialization, IDPF requests a set of PTP capabilities and receives a writeback from the CP with the set of supported options. These options are: - get time of the PTP clock - set the time of the PTP clock - adjust the PTP clock - Tx timestamping
Each feature is considered to have direct access, where the operations on PCIe BAR registers are allowed, or the mailbox access, where the virtchnl messages are used to perform any PTP action. Mailbox access means that PTP requests are sent to the CP through dedicated secondary mailbox and the CP reads/writes/modifies desired resource - PTP Clock or Tx timestamp registers.
Tx timestamp capabilities are negotiated only for vports that have UPLINK_VPORT flag set by the CP. Capabilities provide information about the number of available Tx timestamp latches, their indexes and size of the Tx timestamp value. IDPF requests Tx timestamp by setting the TSYN bit and the requested timestamp index in the context descriptor for the PTP packets. When the completion tag for that packet is received, IDPF schedules a worker to read the Tx timestamp value.

idpf: add support for Rx timestamping
Add Rx timestamp function when the Rx timestamp value is read directly from the Rx descriptor. In order to extend the Rx timestamp value to 64 bit in hot path, the PHC time is cached in the receive groups. Add supported Rx timestamp modes.

idpf: add Tx timestamp flows
Add functions to request Tx timestamp for the PTP packets, read the Tx timestamp when the completion tag for that packet is being received, extend the Tx timestamp value and set the supported timestamping modes.
Tx timestamp is requested for the PTP packets by setting a TSYN bit and index value in the Tx context descriptor. The driver assumption is that the Tx timestamp value is ready to be read when the completion tag is received. Then the driver schedules delayed work and the Tx timestamp value read is requested through virtchnl message. At the end, the Tx timestamp value is extended to 64-bit and provided back to the skb.
